In this embodiment I einplo i. A frame attached to the body of thetypewriter and consisting of two upright main brackets N connecting.which are two square or other suitable rods P and Q, placed parallel toeach other sind :it right a les to the brackets. The rods pass throng.and extend beyond. the brackets so that milled disks X X or knobs orgearing forroteti the same may be att-ached thereto at 'ne en as shownorat both ends.

The rod or shaft P is square, but ismounted-"at ts ends for`revolution. The rller-Dinay be hollow and ineither end is l ai'nietalibush with a square center through I which thefro`d P passes. The bushes projectfa` shortv distance and to them arefitted theltwobrackets L which support the roller 4 0 E, .,Whi ch maybesolid and of which the piv- Q ot'al', extremities project into andbeyond *i fbearings 'in' the'brackets L. Knobs or equiv-v alent-'meansfor rotating the roller E when reqi'iiredj may be provided. The No. 1car- :rier- .i's soarranged that the most forward partait vthe roller Dis vertically above and the r'nost forward art of the roller E is un--der"i'iid slightly in advance of the typing pointofthe typewriter. Thewhole ofthe partsfof.thiscarrier are so arranged that the roller Dl'an'dthe rod P shall be capable ot' ,mutual v rotary motion; the roller Eshall be capable-of separate rotary motion; and the whole-carrier caable of horizontal motion ,5 along" the rod within the limits of theframe.4 Thebrackets'L are fixed on a carriageitnot shown) connected tothe escapeiiientinechanism of the typewriter. 13. 'A carrierNo. 2).supported by the rod v 60 ,Qi and consisting of tv i-'olrollers AA andB placedv parallel toeach other and to the rod Pand connected to eachother by an endless band Y extending practical-ly the full length of therollers. T his carrier No. 2, whichI is ccnwcted to travel with thetypewriter car- ,ject a short distance and upon them are susringe, usedpartly for the purpose of linet'ecding and otherwise controlling aworksheet Z) which underlies the main work-sheet o, and is intended toreceive ty e impressions which are duplicates of tiose made upon thesheet o. These duplicates may be iliade either by -iiiterposition of anordinary carbon sheet or by the use of a special inkribbon mechanism,which will presently be described. The forward roller B is a revolubleplaten, and occupies a position-between the upper and lower rollers DVE,which control the main work-sheet a. will presantlybe seen, the platenB, which controls the underlying work-sheet 1),.4 can be dropped out` of'printing position, so that no duplicates will be made thereon of thetype impressions which are produced upon the outer sheet and a devicewhich supv ports or backs the sheet a, so that it may receive the typeimpressions at such times, will now be described, with its associated devices. The carrier No. 2 also comprises a meta? platen bar C, referablyfaced with rubber or other suita 1e material, parallel 90' to the rod P,and two end brackets M. The

roller A may be hollow and in either end is a metal bush with a squarecenter through which the rd Q, passes. The bushes propended the two endbrackets M which support the roller B and the platen bar C. The' rollerB may be solid and its pivotal extremities project into bearings in thebrackets The whole of the parts of this carrier are so arranged that theroller A and the rod Q shall be capable of mutual rotary motion which bymeans of the endless band will be communicated to the roller B'; and

the roller B and the platen bar C shall be 105 capable of oscillation ina path which is part of the circumference of a circle de scribed aboutthe center of theerod Q so that alternately a point on the roller B anda point on the platen bar C shallbe presented at a point, which-isiminedia-telybehind the typing point of the type Writer; and further thewhole carriershall be capable of horizontal sliding motion along the rodQ within the vlimits of the frame.

The brackets M are joined by the platen bar C and forni a frame hingedto swing up and down in the manner just described. This frame isconnectibleto the-typewriter carriage by means to be presentlydescribed, 12b so as to travel with said carriage; said frame, togetherwith the revoluble platen B, fixed platen (Tand feed roll A, being alsocapable of independent adjustment in a direction longitudinal of theplateiis.

AnA elevating and depressing attachment supported by the mainbrackets N and consisting of two round rods R and S placed parallel toeach other andto the rods P and "Q". and levers T, T', 'If-zcounectingthem 130 together, the levers T being fulcrumed lat T* in the endbrackets N. The ends of the rods R land S project through slots in thebrackets N the rod R passing above the roller D and through two guiderollers H described later. T he rod S passes between the roller A andthe roller B and through a circular hole ircach ofthe brackets M. Thewhole of the attachment is so arranged ,that he rod R can be alternatelyelevated and 'depressed in a vertical direction and to a distanceregulated by the length of the slots in the brackets N; that suchmovements of the rod R shall be communicated by the Vmeans of the leversT, T, T2, to the rod S so asto cause the rod S to oscillate in a pathwhich is art of the circumference of a eircle described about the centerof the rod Q.; the rod S in turn communicates motion to or shifts theroller B and the platen bar Cwby means of the brackets M and so producesthe oscillation ofthe roller B andthe platenbar C previously referredto, and into Ill their centers and are placed immediately 1h front ofthe two spools G. ers H are `fitted with flan es set apart at a Theguide rolldistance equal 'to the 'wi th' of the carbon ribbon or inkribbon. From the guide rollers ll are suspended the two-tracks J whichare nngles to jboth.

maintained inl a vertical position immediately under the guide rollers H-by means of projections from the brackets L. The ribbon tracks J arecut' away at their lower ends at an angle of 45 degrees to enable theribbon to Vbe doubled around .and passed from one ribbontrack to theother at right connected at their lower ends by the ribbon guide bar Kwhich' ,passes in front of and parallel to the rollerB. This guide bar Kias a groove cut in its upper edge along which the carbon ribbonis drawnand whic I sheets whenthe attachment is elevated'. The

serves to keep the ribbon straight as otherwise it might buckle/or curland so fail to be inserted between the original andl copy carbon ribbonis plaeed'in position by` be- .ing wound around the left hand spool fromwhich it passes over the left hand guide roller, downl the left handribbon track J, along the groove of the ribbon guide bar K, up the righthand ribbon track J. and over the right hand guide roller on to theright band spoolor vice versa. The whole of the attachmentl is soarrangedytl'iat, except -the The ribbon tracks J are .two spools G, itcan be alternately elevated will hold the ribbon immediately 'behind afhorizontal line drawn parallel to the roller B through the typing pointof the' type writer, and between the typing point and themostforward'point of the roller B; and that the whole attachment willbecapable 'of horizontal mtionalong the rod R in company with the carrierNo. 1.

To type on the originalsheet a without giving a carbon impression on the copy sheet b it isnecessary to depress the roller B and the platen bar C which causes 'thecarbon ribbon and the copy sheet to be lremoved from contact with theoriginal sheet and' the platen bar C to be brought into contact with theoriginal sheet a immediately the typing point of the typewriter. T heplaten bar C then provides the.. necessary solidity key being struck thecharacter thereon but lill notgive'an pression elsewhere.' l

8. To'obtan duplicate of either oiginal or copy,' it. is necessary toinsert in the pan ticular carrier and behind the originalA sheet or copysheet an additional sheet of paper and a sheet of carbon paper-in themanner conunonlyemployed at present.

9. To 'type on any selected point of the 'riginal sheet aand obtain acarbon impresion/on any selected point of the copy sheet ,"lt 1snecessary to present the selected points at and immediately behindthe-typing point of the type writer.- This is' do'ne by disconnectingthe two carriers and sliding each horizontally until the .selected4points are in vertical line directly behind -the typ-'.
